2021-05-28crypto: qat - report an error if MMP file size is too largeJack Xu1-4/+2
Change the return status to error if MMP file size is too large so the driver load fails early if a large MMP firmware is loaded.

2021-04-16crypto: qat - enable detection of accelerators hangWojciech Ziemba9-1/+99
Enable the detection of hangs by setting watchdog timers (WDTs) on generations that supports that feature. The default timeout value comes from HW specs. WTDs are reset each time an accelerator wins arbitration and is able to send/read a command to/from an accelerator. The value has added significant margin to make sure there are no spurious timeouts. The scope of watchdog is per QAT device. If a timeout is detected, the firmware resets the accelerator and returns a response descriptor with an appropriate error code.

If the ae mask is not identical for all devices of the same type then the arbiter mapping returned by adf_get_arbiter_mapping() may be wrong.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers1-1/+2
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

Change the API and the behaviour of the qat_hal_start() function. With this change, the function starts under the hood all acceleration engines (AEs) and there is no longer need to call it for each engine.
